MARINE DRAG.

SPECIFICATION forming part of Letters Patent No. 289,224, dated November27, 1888.

` Application mea .um 1:, was. urban.)

To a/ZZ whom it may concern: Beit known that I, AMBRosE J. CLARKE, ofBrooklyn, Kings county, and State of New York, have invented a newand-useful Im-` provement in Marine Drags, of which the fol-` lowing isa full, clear, and exact description. Reference is to be had to theaccompanying j, drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts inall the gures.

Figure l is a sectional side elevation of my` im rovement. Fig. 2 is afront elevation of I the same, partly in section, through the line 'linefy y, Fig. 3. of the wings when closed.

the heaving of vessels to.

The invention consists in amarine drag conl y structed with a shankprovided with a stationi the edges of triangular plates, having theother l resistance of the water.

ary runner, to which are hinged the ribs, and

` a movable runner, to which are hinged the stretchers.

The said ribs and stretchers are hinged to each other, and to the ribsare hinged edges of the adjacent plates hinged to each other, wherebythe drag will be opened by the To the outer end of the drag-shank and tothe trip -line are attached i the ends of a chain, the weight of whichwill hold the trip-line below the ribs and plates, so that thesaidtrip-line will be kept from being fouled, as will be hereinafter fullydescribed.

A represents the shankof the drag, whichI prefer to make square incross-section, and to the outer end of which is secured, by rivets,collars, or other suitable means, the stationary i runner B.

To the runner B are hinged, by awire ring, l

` ner that the said plates can fold inward.

To the corner of each alternate wing E, at

the joint midway between the ribs D, is attached a small plate, Q, theend of which projects beyond the saidedge, and is bent at an obtuseangle, so that the outer side of the corner of the other wing will restagainst the said end 5 5 when the drag is opened, the said platesQservingas stops to prevent the wings from folding in the wrongdirection, and thus preventing the drag from closing snugly when thedrag is reversed and is being drawn in.,i

To the' outer ends of the ribs D are hinged, by clevises or lugs F, orother suitable means, the outer ends ofthe stretchers G, the inner endsof which are hinged, by a wire ring, H, or other suitable means, to themovable runner I, which slides upon the shank A, and the outwardmovement of which is limited by a collar, J, or other suitable stop,attached to the said shank A.

To the inner end of the shankA is attached,

by a clevis, K, or other suitable means, the end of a hawser, L, theother end of which is secured to the vessel.

To the outer end ofthe shank A is secured, by a clevis, M, or othersuitable means, the end of a chain, N, which is made longer than theribs D, and has a heavy ring, O, .attached to its free end.

To the ring O is attached the end of a line, l?, extending to thevessel.

With this construction, when the drag is to be used, it is thrownoverboard folded, as shown in Figs. 3 and 4, a suitable length of thehawser L is paid out, and the hawser is then secured to the vessel. Whenthe drag is put under strain by the drifting of the vessel, theresistance of the water opens the said drag into the position shown inFigs. l and 2, so thatthe water will offer a sufficient resistance tothe drag to hold the vessel to the wind. When the drag is to be takenin, the line P is drawn upon, which swings the drag around, so that lIOO of the shank A, having stationary runner B and movable runner I, thehinged ribs D, the hinged plates E, and the hinged stretchersG, as setforth.

2. In a. marine drag, the' combination, with the shank A, the runners BI, the ribs D, and the stretchers G, of the triangular plates E, hingedto each other and to the ribs D, sub stantially as herein shown anddescribed, whereby the drag will be opened by the resistance of thewater, as set forth.

3. In a marine drag, the Combination, with the hinged wings E, of theangular stop-plates Q, substantially as herein shown and described,whereby the said wings are kept from folding 15 in the wrong direction,as set forth.

4. In a marine drag, the combination, with the shank A, runners B I,ribs D, stretchers G, hinged triangular plates E, and trip-line P, ofthe chain N, substantially as herein shown 2o and described, whereby thesaid trip-line will be kept from being fouled, as set forth.
